[F] I used my best friend’s nerdy brother as a stress relief toy…

I wasn't planning to fuck anyone that night.

I mean, I wanted to, don't get me wrong. It had been a while. But unfortunately it wasn't that kind of night; my friend Cara had recently broken up with her boyfriend, and the idea was to help her get over it. Shots. Dancing. Loud music. You know the drill.

By midnight, Cara was gone; drunk, slurry, slumped against the window in the Uber, way too drunk to text him. Mission accomplished.

When we got back to her place, she passed out in the bed, arm thrown over her face. I straddled her and took off her clothes, her huge boobs spilling out of her tiny top, pulling down her shorts and panties and wrapping her up in a blanket. She had a great body, but it was nothing I hadn't seen a hundred times before.

With Cara secured, I focused on myself, taking off my party clothes and grabbing her white satin robe. I didn't bother with panties–what would be the point? Oven fries and chicken nugs were my next target, followed by crashing out on the couch.

What I forgot–until I stepped into the living room completely naked except for a tiny white robe–was that her little brother was staying over too.

Okay, not little little. He's twenty-seven, and I'm thirty-two. I still think of him as a little brother but I guess he isn't that little anymore.

Anyway, he looked up when I walked in, startled, headset around his neck, controller still in hand. His game was paused. I think it was something with swords and spells–whatever guys like that play at one a.m. when they think no one's watching.

"Oh shit! Hey, Owen! Forgot you were staying. How's it going?"

"Uh…good thanks." His eyes flicked from the screen to my legs, the tiny robe barely covering the curve of my ass. "You guys just got in?"

"Yup!" I nodded. "Sorry about the outfit," I giggled. "If I'd known you were up I'd have put on some panties."

Owen laughed, but I could hear the tension in it, and although he tried to play it cool, I once again caught the flick of his eyes down breasts, big and heavy and slightly exposed where the robe had come open, revealing the kind of cleavage that made even the biggest cocks disappear. It would've been easy to pretend I didn't notice the tension between us, to just say goodnight and walk back to Cara's bedroom.

Instead, I thought about riding her geeky brother's face.

But it wasn't my fault!

I was already horny when I came in; all that dancing, the brush of strangers, the tight dresses and compliments and frustration of going home alone. My body was buzzing, and I was trying to shake it off; but this kid sitting there, his jaw tight, eyes wide, fidgeting with the buttons on his controller like he didn't know where to look…well…I was triggered.

"Playing anything fun?" I asked, moving around the kitchen as I made myself a cup of tea, letting my robe open a little more at the top. Not enough to be obvious, just enough to force him to imagine what my tits would look like naked, bare and heavy and practically aching with the need to be touched.

"Umm…just a fantasy MMO type thing."

"You always stay up this late?" I asked, moving toward him and sitting down on the edge of the couch.

"Kind of, yeah." He looked a little flustered by my proximity and nakedness. Honestly, it made me want to fucking use him.

"You're good at it?" I asked.

"Kind of," he muttered. "It's kind of boring though. Let me switch it over…"

I smirked as he fumbled with the remote and changed the channel, the screen turning into what looked like a pretty terrible rom-com. He watched the screen with feigned interest, as if his sister's best friend wasn't completely naked beneath her robe beside him.

"You're blushing," I said with a giggle. "Are you embarrassed?"

"I…uh…it's just…" he floundered.

"Relax," I murmured. "It's just me."

But I wasn't just me. Not that night. I was wound up and wet and mean.

I'd spent the last month being polite and patient and not climbing on top of anyone, and it was catching up with me fast. I could feel my pulse in my clit, my breasts, the soles of my feet. I wanted contact. I wanted release.

And I wanted it now.

"Tell me," I said, putting my naked feet up on the coffee table and exposing my thighs and the side of my ass to him, casually, as if I didn't know what I was doing. "Can you keep a secret from your sister?"

He froze. "Um…yeah….I mean, I guess."

His voice cracked slightly. I smiled.

"Good." I played with the edge of the robe a little, as if I was doing it absently, as if it wasn't getting wetter every time he tried to sneak a glance at my almost completely exposed breasts. My nipples were so hard already, all I could think about was pinning him down and pushing them into his mouth, making him suck them as rode his cock.

Instead, I opened my legs a little. "Okay, well my secret is that I really wish I had found someone to fuck me tonight. Do you ever feel like that, Owen? Like…you just need to fuck so badly?"

He swallowed. "Y-yeah," he said finally. "Sometimes."

"Sometimes," I repeated, smiling. "God. I feel like that all the time lately. It's actually getting kind of ridiculous. It's like my pussy is always wet at the moment."

And it was true. My thighs were warm and sticky where they met. My nipples were aching and tight. I was full of that particular kind of horniness that feels like desperation. Owen made a sound in his throat.

"Like…even right now, Owen." I continued, letting my knees open and close, forcing him to imagine my smooth wet pussy lips pushing together and then releasing, opening, dripping. "It's sooooo fucking wet."

Owen's jaw was clenched. He had gone bright red.

But, despite his embarrassment, his cock was rock hard. I could see it straining against his sweatpants.

"When a woman feels like that, I think she should just…take what she needs. What do you think?"

"Uhh…yeah…I guess."

"Like for example right now. I could just pull your cock out and ride you until I was done with you…."

"Sarah…" he said, his voice full of reproach. "What about my sister?"

I stood, slowly. My robe fell open completely, and I didn't bother to hide myself. I let him see everything–the full swell of my breasts, the curve of my stomach, the slick between my thighs catching the low light from the TV.

"Lie back," I told him.

He looked at the bedroom door for a moment, then at my body, and then obeyed.

Wordlessly, I straddled him, this time further up, my knees on either side of his shoulders. My pussy hovered just above his face, and I saw his eyes go glassy.

"I want your mouth," I said. "You're going to make me cum, Owen. And you're not going to stop until I say so."

[As always, this post has gone on a bit long so I will type the rest up if people want to hear it!]
